Abstract

To permit one to simultaneously observe and record details of a welding operation, a conventional welder's mask 10 is al-tered by (1) removing a narrow 5/32" strip 12 from the lower peripheral area of the filter 14, (2) reducing the total thickness of the filter/cover glass combination to improve the visual angle, and (3) adding a 2" radial cutout at the neck portion 16 of the mask.

To permit one to simultaneously observe and record details ofa welding operation, a conventional welder's mask 10 is al-tered by (1) removing a narrow 5/32" strip 12 from the lowerperipheral area of the filter 14, (2) reducing the totalthickness of the filter/cover glass combination to improve thevisual angle, and (3) adding a 2" radial cutout at the neckportion 16 of the mask.

This alteration gives one 3°of unobstructed vision to observesupplemental elements of the welding operation without sac-rificing the eye protection afforded by the entire filter areawhile observing the quality and technique at the point of thearc. The 2" radial cutout at the neck portion 16 providesadequate clearance to simultaneously read and record data.
